Increase HTTP Post maxPostSize in Spring Boot

Question

I\'ve got a fairly simple Spring Boot web application, I have a single HTML page with a form with enctype=\"multipart/form-data\". I\'m getting this error:

Answer 1

The error here is not caused by max-file-size or max-request-size (as pointed out) but rather the container-specific max-http-post-size property. For tomcat (the default container), you can set:

server.tomcat.max-http-post-size: 10MB

Jetty:

server.jetty.max-http-post-size: 10MB

Undertow:

server.undertow.max-http-post-size: 10MB

This has the same effect as OP's answer here, but via application.properties which is much more preferable.
